Name: Saten Ruiko
Age: 13
Species: Human
Gender: Female
Personality: A normally outgoing and friendly person, who is superstitious and has a knack for getting involved in things that aren't usually her problem. She is good at reading the atmosphere and a bit shameless. While those traits have remained, extended usage of the Level Upper program has had some effect on her, making her jealous of the power that she has gained, and determined to keep it at all cost. But in spite of this, she is still a good person at heart. 
Bio: [hider=Slight spoilers for Certain Scientific Railgun Season 1]
Born outside of Academy City, Ruiko moved there at a young age after she decided to become an Esper, leaving her family behind in the process. In spite of her desires though, she was unsuccessful in this, and was classified as a Level 0. Nonetheless, she was able to become friend with Uiharu Kazari, and then later on Misaka Mikoto and her friend Kuroko.

Surrounded by such people, it was only a matter of time before the normally apathetic Ruiko became envious of the fact that all her friends had powers while she didn't. Hearing a rumor about a program called the 'Level Upper', she investigated and managed to obtain a copy, though she refrained from using it at first. This was changed by two factors, the first being Mikoto's claim that levels and abilities weren't important, when they were the entire reason that Ruiko had come to Academy City in the first place. The other was being caught helpless during a battle between Trick and Kuroko, where the latter triumphed but was injured.

In the aftermath of that fight she used the Level Upper program, and manifested the Aero Hand ability. While keeping it secret at first, Ruiko was forced to reveal her ability during an attack by Skill-Out, where she was able to save some people and aid in putting an end to the fight. But this led to a confrontation between her and the present Mikoto, during which her MP3 player was fried by her Electromaster ability. 

Ruiko ran off, and was eventually able to use her skills to track down the creator of the program, Kiyama Harumi. Harumi gave her a new copy of the program, and after Ruiko informed her that Mikoto was looking for her to put a stop to the Level Upper experiments, she agreed to let Ruiko help her in stopping Mikoto, or at the least delaying her. 

At first this took the place of misinformation, Ruiko spying on Mikoto and informing Harumi of her efforts, and leading her along false trails to dissuade her and Judgment's investigations. This lasted for some time until she was discovered, and forced to flee to Doctor Harumi's lab to avoid arrest by Judgment. There she helped to prepare to defenses, to await the inevitable.

Abilities: 
[u]MP3 Player[/u] - A device for playing music, which contains the Level Upper program. This program can stimulate brainwaves in such a way so as to allow for the rapid development of Esper abilities. 

[u]Aero Hand[/u] - An Esper ability that allows one to ceate ejection points for air on an object with a touch. This can be used to propel objects through the air, or to simply create blasts of air when an object cannot be moved. There tends to be a delay depending on the user, and the strength is also dependent on a users level. 

Saten can only use this ability while under the influence of the Level Upper program, but while so she tends to display abilities around that of a Level 3
